Re: NNUE

This mean that this programmer must come from another world, There is 2015 Fabien Letouzey is writing the wonderful program. The program is called Scan. Scan has own beautiful ideas and has an opened code. He is playing the program wonderfully and is getting the top one spots at the Olympics. Wheth...

Re: NNUE

Who spoken of copying idea or plagia code? each program has his own eval and others things that make his style of playing: Kingsrow, Scan, Damage, Maximus, Ares, Dragon, Truus, Flits and Mobydam haven't the same playing style. But all of them are based on, by caterogy, on a kind of algorithm, so CO...

Re: NNUE

Hi Krzysztof, In year 1990, we never thought that another program will be stronger than Truus, and then came Buggy, Damy, Kingsrow, Scan without forget Damage , Dragon, Maximus. All these stronger programs are being innovated, creation not really exist, we perfom something that already exist to hav...

Re: NNUE

My 5 cents... If you want to write the best program , then stick to the patterns based solution as implemented in Scan and Kingsrow. If one want to embark on the new developments in neural networks (both SW as HW), and use draughts as a test environment, then try nnue. Bert I am only giving some th...

Re: NNUE

Sidiki, I think the situation with International 10x10 Draughts is different, compared with Chess. First of all with Draughts we might be already quite close to the Draw Black-Hole, with excellent programs as Scan, and Kingsrow. So with NNUE we will most likely not surpass the current pattern based...

Re: NNUE

This morning I analyzed some of the losses of yesterdays match and I found that they were not all caused by bad evaluation of the NN. There was a problem with my quiescence search, several weeks ago I did some experiments with my q-search and I simply forgot to remove that code. So I reran the matc...

Re: NNUE

From Ed I got the information that the current Scan nnue implementation does not work in hub mode. I checked that, and he is (as usual) right. As I mainly play DXP matches with Scan nnue, I only included the dxp option. So I will fix this during the week, and post an update. Bert Thank again Bert, ...

Re: NNUE

Sidiki, the exe file which you need is in the folder x64/release, scan_31nnue.exe (1/16/2021). If you already have a working Scan configuration you can just put it in the folder where the original Scan is. The network (nn_20210110.gnn, 1/10/2021) is in the folder scan_31nnue/data. You need to add t...

Re: NNUE

I also checked the most recent version of Scan nnue. The match against Kingsrow was with the traditional settings, so 1 min/65 moves, 6p DB, 6 cores no book. Result (perspective KR) 3W, 0L, 151D, 4U I analyzed the 4U, with outcome, game 53 draw, game 133 win Scan nnue, game 141 draw and game 147 al...

Re: NNUE

Herewith the link to the dropbox folder with the sources of Scan nnue. I will post later some side notes. I would like to thank several people who without this was not possible. First of all Jonathan for starting to implement nnue in his checkers program, and I used his code as base , and you can s...

Re: NNUE

The test with multicore seemed to work. The usual settings 1 min/65 moves (so equal time control), 6p DB, no book, and both 6 cores. Result KingsRow - Scan nnue (perspective KR): 158 games, 6W, 0L, 152D, Elo difference is 13. During the weekend i will try to make the Scan nnue source available for ...

Re: NNUE

Sidiki, you are welcome. As this is the last day of my Xmas-holiday, from now on progress (if any) will be much slower. Sorry for that. Bert Hi Bert, Happy New Year to you and others programmers. Understood, we will waiting for the new progress done by Damage. What can explain this gain of strength...

Sidiki, here they are.

There were 2 unknowns which were both a win for Kingsrow (game 48 and game 84), for which I corrected the scores in the file.
Result 22 W Kingsrow, 136 draw, Elo difference 49.

Bert
Thanks very much Bert.Thanks

Re: NNUE

With 256 neurons in the first layer the match result was (perspective KingsRow) 22W, 136D. Elo difference 49. Not sure if this is within the margin of error, but if one thinks in a positive way, slowly improving day by day :D Bert Great result with Damage's NNUE; i think that, as i said, we must ha...
